Steve I in 2014 did a paper for SMPTE, Belden contributed 100m reels of cables to the project, both TP and coax of 18 different types. We ran digital audio signals with rate to 24.576 MHz and looked

Of course! After a few drinks and too much to eat, at 1:30 AM while being a one finger typist, with the computer accepting anything I type, viper sounds like wiper anyway! I am glad I did not type

I happen to have the board Layouts for 475 and 475A and after a cursory look, they appear to be almost identical. They are, as someone else noted, completely different from the 465, but they do

No but it will sound fantastic, especially when you use oxygen free Tektronix Gold Plated Probes... Harvey

I think the best compromise might be the 3 pole midget twistlock from Hubbell, as it will give me a grounded connection, and the modification will be the lest conspicuous: slightly enlarging round

When I came across this problem (and after an unsuccessful search for my genuine ancient line cord), I took one of those rubbery 3-prong-to-2 prong adapters and, with a sharp knife, cut off the female

Yes, C1374 is in a good place to explain a lot of what you're seeing. But schematics aren't board layout, and the TekWiki links for 475A don't seem to have the board layouts. So I don't know how

Probably not. Posting for a friend. :-) HAPPY NEW YEAR to everyone Bill

An IEC would definitely need an adaptor plate. The less common type with mounting holes above and below rather than out to the sides might be a better fit. The other type I've used (again this betrays

Thanks Bruce - 'General Electric' extension cords is giving some good hits. I guess these weren't grounded via their AC socket?

no ground on the ones I serviced, I changed all to 3 pin IEC ( they are/were on other non TEK equipment) as it was required for safety...IMO was not needed but ya do as ordered. above my pay grade.

Thanks! An IEC socket /almost/ fits, but would require a little bit of filing, and maybe a plate to fill in the remaining gaps. I'll take a look at the EP - I think I remember seeing them on consoles

The cable female connector was made by several manufacturers, most I have seen were General Electric. I have never seen one with a grounding contact. You can also search for an older extension cord

Here in the UK (where NEMA connectors of any type aren't really used at all) I've seen Tek scopes that have been retroftted with EP4 power inlets. Coming from a broadcasting background I have plenty

Does anyone know of a source for the cable-end receptacle that mates with the plug shown in this photo https://w140.com/tekwiki/wiki/514#/media/File:Tek514-lineSocket.jpg The inside is metal, and I

Happy New Year to all! Resolve the condition and function of R1375 before you move on. What you describe above sounds suspicious to me. After that, there are some other component to check as well.

Hello, these people might be useful: www.krystaly.cz/en/Products/Crystals No affilation. But I speak a few words of Slovak and are in the region...so if I can help, I will in the frame of my

One thing my engineer buddy did in the lab we used was to look at the ¡°speed of light¡±. He took a reel of coax we had gotten to run some Ethernet links. This was before twisted pair took over from

Larry, I think this approach makes sense. It will not be the ¡°cheap¡± way to make this happen, but it will likely produce the best results. As I had already stated, I would be up to helping out
